Summary: | Maintenance and Update Frequency: continual Statement: Voyage underway data are acquired by a standard suite of instruments and processed using standard methods as described in relevant voyage documentation. Credit Multiple contributors from CSIRO Oceans and Atmosphere Credit CSIRO Oceanography Credit CSIRO Fisheries and Marine National Facility. The CSIRO O&A Optimized Voyage Tracks displayed in the WMS associated with this record are derived from underway GPS data collected since 1986 by Australia's Marine National Facility during research voyages. For most of these voyages, five minute underway digital data is available. The underway data set typically includes GPS location, Sea Surface Salinity and temperature, and Meteorology Station data. Later voyages also recorded digital echo sounder data. Individual metadata records have been created for each research voyage. The data is held in the CSIRO O&A Data Warehouse, which currently holds underway GPS data for more than 200 voyages.
